The synthesis of 2-methyl-and 2-Styryl-6-bromo-7, 8-benzochromone and 2, 6-Dimethylchromone and their reactivity towards cyclo-addition reaction under Diels-Alder conditions and towards nucleophilic and electrophilic reagents are studied.
The mode of formation and structure of the various products are reported using IR, 'H NMR, Mass Spectra and elemental analyses.
